Specification of Letters Patent.

Patented Sept. 29, 1909.

Application filed April 10, 1908. Serial N 0. 426,390.

To all whom it may concern:

' Be it known that I, WESLEY EDWIN SPAF- FORD, of the city of Toronto, in the county of York, in the Province of Ontario, Canada, have invented certain new and useful Imrovements in Horseshoes, of which the folowing is the specification.

My invention relates to im rovements in horse shoes, and the object of the invention is to devise a simple, convenient, strongand durable shoe in which the sharp calks may be readily removed when it is desired to have the horse travel on a smooth shoe and readily replaced again when desired without having to remove the shoe and in a minimum period of time.

The invention includes the novel features of construction and arrangement of parts hereinafter described and particularly set forth in the appended claim.

A horse shoe constructed in accordance with my invention is illustrated in the accompanying drawings in which,

Figure 1, is a perspective view of a shoe in the reverse posltion' with my attachment connected thereto. Fig. 2, is a perspective view of the attachment with the clamping screw removed. Fig. 3 is a perspective view of the toe clip. Fig. 4 is a perspective view of a detail of one of the side pleces. Fig.

' 5 is a perspective view of the turning screw.

Fig. 6 1s a central longitudinal sectional view from front to rear of the shoe. Fig. 7 is a cross section of the shoe taken through the clamping screw.

In the drawings like letters of reference indicate corresponding parts in each figure.

A is the smooth shoe provided with the usual flat heel calks.

B is a central toe clip, which is designed to straddle the toe of the shoe horizontally, the said toe clip having as indicated in Fig. 3, the arc-shaped overhanging iece B provided with end bosses or e argements B having holes 1, the reversely turned d(;611d-.

ing arc-sha ed ortion B designed to t the inside of tlie sfioe at the toe and provided with lugs B to fit on top of the shoe and shown lowermost in the drawing on account of the piece being inverted.

C and O are the side pieces, which are substantially arc-shaped in form or more,

proiperly conform to the shape of the shoe an are provided with end holes 2 designed to register with the holes 1 in the toe clip when said ends of the side pieces are fitted under the holes in the toe clip as indicated in Figs. 1 and 2. In this position the calks 3 are provided with flat flaring ends 3 as indicated by dotted lines in Fig. 6, which calks extend through the holes 2 and 1.

4 are the end heel calks, which extend through holes 4, the calks being provided with flat flaring heads, which abut the horse shoe proper as indicated in dotted lines in Fig. 6. The piece C is provided with a square socket 0 formed in the projection 0 the portion 0 of which extends on the up er,

side of the shoe. The piece O is provi ed with a'projection 0 having a round socket O theportion 0 of the projection extending above the shoe.

In Fig. 7, the shoe is shown in the inverted position and I have referred particularly to this figure in describing the above construction.

I The socket C is a tapered socket and into such socket fits the tapered head D of the screw D. D is a screw socket, which in Fig. 7 I show partly broken away and in section. The screw socket D is provided with a round tapered head D which fits in the round socket C.

To place and secure the pieces O O and B in position the piece or too clip B is inserted as indicated in Fig. 6, so as to extend above and below the shoe, the calks 3 being held in place by abutting the shoe. The pieces 0 and C are spread out over the sides of the shoe and the connecting turn screw is fitted with a square tapered end D in the square socket C and the round tapered end D in the round socket O and the sidedportion of the socket D is turned by a wrench until the two side pieces are spread sufiiciently far apart, so as 'to force the projections C and O to straddle the shoe and securely hold the pieces 0 and O and B in position. The shoe A, of course, is fitted on to the foot primarily and the attachments B O C hereinbefore described it will be readily seen can be not only attached but quite as easily detached by following the reverse operation to that immediately above described.

Such an attachment to horse shoes as that described is very simple, cheap and efiicient and convenient dispensing with reshoeing a horse for icy or slippery weather.

What I c aim as my invention is:

1. In a horse shoe, the combination with the toe piece having the arc-shaped upper 7 portion and lower projections and intermediate connection adapted to fit the inside of the toe portion of the shoe, of the side pieces adapted to fit on to the sides of the shoe and having the ends extending underneath the ends of the toe clip and the toe calks extending through holes in such ends and abutting the shoe, and the heel calks extending through the heel ends of the pieces and abutting the shoe and means for fastening the toe clip and side pieces in position as and for the purpose specified.

2-. In a horse shoe, the combination with the toe piece having the arc-shaped upper portion and lower projections and intermediate connection attached to fit the inside of the toe portion of the shoe, of the side pieces adapted to fit 011 to the sides of the shoe and having the ends extending underneath the ends of the toe clip and the toe ealks extending through holes in such ends and abutting the shoe, and the heel calks extending through the heel ends of the pieces and abutting the shoe, projections formed on the side pieces and extending above the shoe, a square tapered socket formed on one projection, a round tapered socket formed on the op osite projection, a square tapered headed bolt extending into the square socket, an internally threaded socket designed to lit on to the bolt and provided with a round tapered head. as and for the purpose specified.
